BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to video game control systems and, in particular, to systems and methods for interfacing a simulation device to a video game device, so to allow the simulation device to control one or more functions of the video game.

2. Description of the Related Art

Video games are a widely popular source of entertainment. According to some estimates, nearly one half of all U.S. households own a video game console or a personal computer by which video games can be played. Video games are available in a wide variety of genres, including role playing games, driving simulations, and sports, providing a source of relaxation and immersion for users of many interests. Increasingly, though, video game users are seeking greater levels of immersion and activity in their game play.

To meet this need, systems have been developed which allow a user to simulate an activity and measure some portion of that activity to control a video game played on a video game player. In one example, U.S. Pat. No. 5,362,069 to Hall-Tipping (“Hall-Tipping”) describes an apparatus usable with an exercise device, such as an exercise bicycle, and a video game player. The apparatus utilizes a sensor built into the bicycle to sense an output level of the bicycle, such as pedal speed, and generate an output level signal indicative of the user's pedal speed. A joystick controller may also be utilized to generate signals to control the play of the game. The signals are transmitted to a processor by an interface and combined into signals which are output to the video game player to control operations of the video game.

The design of the Hall-Tipping device presents numerous disadvantages for a user, however. Notably, the Hall-Tipping device employs an interface which receives a number of cables to allow communication between the exercise bicycle, the joystick and the video game player. The proper configuration of these cables may be difficult for a user, particularly younger users or technically unsophisticated adults, to set up. Furthermore, the large number of communication cables utilized by the interface increases the likelihood of one or more cables becoming detached from the video game player, disrupting control of the game. Additionally, should the interface become lost or broken, the bicycle may not be used in conjunction with the video game. All of these disadvantages may frustrate the user and diminish their enjoyment of games played on the video game player.

In further disadvantage, the Hall-Tipping device allows both the joystick controller and the output of the exercise bike to control the same functions of the game. So configured, users of the apparatus may inadvertently control one or more functions of the game with the joystick when meaning to provide control functions through the exercise device or vice versa. This configuration may therefore interfere with game play also diminish a user's enjoyment of games played on the video game player.

An additional disadvantage of the Hall-Tipping device is the configuration of the sensor. The sensor is built into the exercise device, preventing a user from employing the apparatus with any other exercise device. Therefore, if the exercise device breaks or the user wishes to use a different exercise device in conjunction with the apparatus, the user must purchase a new apparatus and exercise device at significant expense.

In another example, U.S. Pat. No. 6,543,769 to Podoloff, et al (“Podoloff”), describes a snowboard apparatus connectable to a video game player. The apparatus allows a user to perform snowboarding maneuvers and output a signal representative of the snowboard position to an interface circuit connected to the video game player in order to control the play of the video game. A non-standard auxiliary hand controller may also be input into the interface circuit to provide further control functions for additional maneuvers.

The Podoloff device also provides an unsatisfying control configuration for a user. In one disadvantage, the Podoloff device, similar to the Hall-Tipping device, also utilizes an interface to allow communication between the snowboard apparatus, the hand controller, and the video game player, with the attendant disadvantages discussed above. Furthermore, the shape and the position of the controls in the non-standard controller differ significantly from a standard hand controller. Therefore, a user of the apparatus familiar with standard hand controllers must learn to use the new controller. This learning process can be a frustrating and time consuming process which may diminish a user's enjoyment of the game.

These deficiencies in current video game interface designs illustrate the need for improved methods and systems for interfacing a video game with a simulation device which are easy to use and reduce the potential for user error.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 presents a block diagram of one embodiment of a gaming device interface system 102 for use in interfacing a simulation device 108 to a gaming device 104. As shown in FIG. 1, the interface system 102 comprises a sensor 106 and video game controller 110. In general, the video game controller 110 is configured to provide control functions for a game played on the gaming device 104 such as speed or directional movement. The sensor 106 is configured to measure one or more simulation parameters of the simulation device 108, for example, the pedaling speed of an exercise bike, and output a simulation control signal 112 which is representative of the measured simulation parameters to the video game controller 110. Using the sensor 106 in conjunction with the video game controller 110, the video game controller 110 receives the simulation control signal 112 and communicates a controller output signal 114 to the gaming device 104. This design allows the interface system 102 to provide control functions for the gaming device 104 that may include control functions provided by the simulation control signal 112, as well as the video game controller 110. In one embodiment, discussed in greater detail below with respect to FIGS. 3A-F and 4A-4D, the simulation control signal 112 may override one or more control functions of the video game controller 110. Advantageously, this design allows games played on the gaming device 104 to be simultaneously controlled using both the simulation device 108 and the video game controller 110, without the control functions provided by the sensor 106 and the video game controller 100 interfering with each other.

As illustrated in FIG. 1, the gaming device 104 is further configured to provide an audio/visual output signal 116 to a display device 120 such as a monitor or television unit. As generally known, such visual display and accompanying sound can provide an entertaining simulation.

In one embodiment, the interface system 102 can provide control functions for a variety of electronic games and gaming devices 104. In certain embodiments, the gaming device 104 may comprise personal computers. In alternative embodiments, the gaming device 104 may comprise dedicated electronic devices designed to play video games, also known as video game consoles. Examples of such video game consoles may include the Microsoft XBox™ and Xbox 360™, the Sony Playstation™, Playstation 2™, and Playstation 3™, and the Nintendo Entertainment System™, Super Nintendo™, Nintendo 64™, and Nintendo GameCube™. Non-limiting examples of electronic games for which the interface system 102 may provide control functions include exercise, racing, and action video games. Based on the configuration of the simulation device 108 employed, the interface system 102 may provide control functions based on simulation parameters which may include, but are not limited to, a user's speed or pace of running, walking, or biking or motions and maneuvers performed by the user during motoring, skiing, snowboarding, and skateboarding. Embodiments of the interface system 102 employing example simulation devices 108 are discussed in greater detail below in Examples 1 and 2.

FIGS. 2A-2B present front and side views of one embodiment of the video game controller 110. In one embodiment, the game controller 110 possesses a body 202 with integrated handles 204, allowing a user to grasp the game controller 110 during use. Mounted on the body 202 are controls which may include, but are not limited to, thumbsticks 206, directional pads 210, buttons 212, and triggers 214. These controls are positioned on the body 202 within easy reach of the user's fingers and thumbs for use when grasping the controller 110. So positioned, these controls may be actuated in one or more dimensions. For example, one-dimensional actuation may include depressing the button 212 or squeezing the trigger 214, while multi-dimension actuation may include moving one or more of the thumbsticks 206 or directional pad 210 in a combination of up, down, left, or right movements.

The game controller 110 communicates with the gaming device 104 using generally understood electrical standards and software protocols to yield one or more control functions to the gaming device 104 based on actuation of the controls. The control functions provided by each control of the game controller 110 will depend on the type of game being played. For example, the thumbsticks 206 and directional pads 210 may provide control functions such as panning and moving, as they may be actuated in multiple dimensions, while the buttons 212 and triggers 214 may provide control functions such as jumping and braking, as they may be actuated in a single dimension. For example, in a racing game, the thumbsticks 206 and triggers 214 may provide control functions for turning and speed, respectively, while the buttons 212 may provide control functions for braking and the horn.

In one embodiment, the game controller 110 is configured to mimic a standard game controller. As described herein, a standard game controller may comprise video game controllers manufactured for video game consoles such as the Microsoft XBox and Xbox 360, the Sony Playstation, Playstation 2, and Playstation 3, or the Nintendo Entertainment System, Super Nintendo, Nintendo 64, or Nintendo GameCube, or personal computers. For example, the shape, layout of controls 208, and the relationship between controls 208 and control functions of the game controller 110 may generally similar to standard game controllers. Advantageously, this design allows a user of the interface system 102 to employ proficiency they possess in operating standard video game controllers without additional training, enhancing the user's enjoyment when using the interface system 102.

In certain embodiments, the game controller 110 may be further configured to accept an external control signal 216. In one embodiment, the game controller 110 additionally comprises a communications port 220 in the controller body 202. The port 220 allows an external communications link 218 to be reversibly connected to the game controller 110 to provide the external control signal 216. In one embodiment, the external control signal 216 may comprise the simulation control signal 112. As described in greater detail below with respect to FIG. 3, the game controller 110 may be configured to allow the external control signal 216 to override one or more control functions of the game controller 110.

In an alternative embodiment, illustrated in FIG. 2C, the game controller 110 may comprise two bodies 222A and 222B and controls 208. The two bodies 222A and 222B are configured to communicate with each other by a controller communications link 224 in order to provide control functions equivalent to a game controller 110 with a single body 202.

In one embodiment, the signals 112, 114, 116, and 216 and the communication links 218 and 224 described above may be wire-based, wireless, or a combination thereof. The wireless functionality can be facilitated by one or more game controllers 110 being powered by a plurality of batteries. Other embodiments of the interface system 102 employing wireless functionality are discussed in greater detail below.

FIGS. 3A-3D schematically illustrate the operation of one embodiment of the game controller 110 which is configured to accept the external control signal 216. In one embodiment, the external control signal 216 comprises the simulation control signal 112 from the sensor 108. In general, actuation of the controls 208 provides a plurality of control functions 300, while the simulation control signals 112, described in greater detail below, provides a plurality of control functions 300′ to the game controller 110 representative of one or more simulation parameters of the simulation device 108. As discussed in the embodiments below, the game controller 110 can be configured such that the control functions 300′ provided by the simulation control signal 112 override one or more of the control functions 300 provided by the video game controller 110.

FIG. 3A illustrates one embodiment of the operation of the game controller 110 when the simulation control signal 112 is absent. The user of the interface system 102 actuates one or more of the controls 208 of the game controller 110 when playing a game on the gaming device 104. In response, the game controller 110 outputs the least one controller output signal 114 to the gaming device 104 which provides control functions 300, for example, 300A-300D, to the game being played. In this embodiment, the game is controlled by control functions 300 arising solely from actuation of the game controller 110.

FIG. 3B illustrates one embodiment of the operation of the game controller 110 when the simulation control signal 112 is present. The user of the interface system 102 operates both the simulation device 108 and actuates one or more of the controls 208 of the game controller 110. The game controller 110 provides control functions 300A-300D, while the simulation control signal 112 provides one or more control functions 300′, for example 300D′, where 300D and 300D′ control the same function within the video game. In one embodiment, a logic circuit within the game controller 110 detects the simulation control signal 112 and overrides the control function 300D in favor of control function 300D′ (illustrated by an “X” in FIG. 3B). As a result, the game controller 110 provides the gaming device 104 with a controller output signal 114 that provides control functions 300A-300C and 300D′. In this manner, the interface system 102 provides control functions to the gaming device 104 from both the simulation device 108 and the game controller 110. FIG. 3E presents one embodiment of a circuit 304 which provides this control function override for a one-dimensional control, while FIG. 3F presents one embodiment of a circuit 306 providing this control function override for a multi-dimensional control.

In one embodiment, the user may select whether one or more of the control functions 300 of the game controller 110 are overridden by the simulation control signal 112. FIG. 3C-3D illustrates embodiments of the game controller 110 further comprising a switch 302 which allows the user to choose to whether one or more of the control functions provided by the simulation control signal 112 overrides one or more control functions 300A-300D provided by the game controller 110. As illustrated in FIG. 3C, when the switch 302 is in the “on” or engaged position, the game controller 110 allows the external control signal 216 to override one or more control functions 300A-300D of the game controller 110. Thus, when the switch 302 is engaged, the game controller 110 allows both the game controller 110 and simulation control signal 112 to provide control functions to the gaming device 104, as described above with respect to FIG. 3B. As illustrated in FIG. 3D, when the switch 302 is in the “off” or disengaged position, the game controller 110 does not allow the simulation control signal 112 to override one or more control functions 300 provided by the game controller 110. Thus, when the switch 302 is disengaged, the game controller 110 provides all control functions 300A-300D to the gaming device 104, as described above with respect to FIG. 3A.

Advantageously, this user-selectable function control override provided by the interface system 102 gives users of the interface system 102 significant flexibility when using of the simulation device 108 to provide one or more control for a game being played on the gaming device 104. For example, a user of the interface system 102 may use the game controller 110 with the switch 302 in the disengaged position until they are ready to use the simulation device 108, as the plurality of control functions 300′ provided by the simulation control signal 112 are not received by the gaming device 104 until the user engages the switch 302. Additionally, the user can selectively use the simulation device 108 as desired during play. For example, if the user becomes frustrated or tired while using the simulation device 108 to provide control functions 300′ to the game, they may disengage the switch 302 to completely control the game with the game controller 110.

In a further advantage, the design of the interface system 102 promotes ease of use of the interface system 102. In other designs for interfacing a simulation device with a gaming device, a dedicated interface interconnects a game device with a simulation device and a video game controller and is only useful when using a simulation device. As a result, this dedicated interface may become misplaced in the time between uses of the simulation device, as it has no other function, frustrating a user when they desire to use the simulation device. In contrast, game controller 110 of the interface system 102 may be employed independently of the simulation device 108 to provide control functions for a game played on the game device 104 as well as allowing the simulation device 108 to communicate with the gaming device 104. This dual functionality of the game controller 110 decreases the likelihood that the game controller 110 may become misplaced between uses of the simulation device 108 and allows the user to employ the simulation device 108 at any time.

The interface system 102 may be further configured to allow the user to precisely select which control functions 300′ provided by simulation device 108 override control functions 300 provided by the game controller 110. In one embodiment, the sensor 106, the game controller 110, the simulation device 108, or a combination thereof may be configured with user-adjustable switches 302 for each of the control functions 300′ provided by the simulation device 108. Thus, for example, a user of the interface system 102 employing a simulation device 108 which provides control functions 300′ for horizontal and vertical motion may elect to override the horizontal but not the vertical control functions 300 of the game controller 110. Advantageously, this design allows the user to tailor the interface system 102 according to their preferences, further enhancing their enjoyment of the interface system 102.

FIG. 4 illustrates a schematic illustration of one embodiment of the sensor 106. Specific embodiments of the sensor 106 will be discussed in greater detail below in Examples 1 and 2. In one embodiment, the sensor 106 comprises a sensing component 400 and a processor 402. In general, the sensing component 400 is the portion of the sensor 106 which measures one or more simulation parameters of the simulation device 108. The sensing component 400 further outputs a sensing component signal 404 representative of one or more simulation parameters to the processor 402. The processor 402 converts the sensing component signal 404 to the simulation control signal 112 which can be understood by the game controller 110 in order to provide the game controller 110 with control functions 300′ representative of the simulation parameters. It may be understood, however, that in alternative embodiments, the sensing component 400 and processor 402 may be combined in a single component.

In one specific embodiment, the processor 402 converts the sensing component signal 404 into DC voltage levels. In alternative embodiments, the sensing component 400 directly outputs sensing component signals 404 comprising DC voltage levels representative of the simulation parameters. Subsequently, these DC voltage levels can be converted by the processor 402 to equivalent three terminal resistances, commonly referred to as a potentiometers. The three terminal resistances can be input to the game controller 110 to override one or more three terminal resistors whose resistance can be varied by the user through actuation of controls 208 such as the thumbsticks 206 or triggers 214.

In a further embodiment, the user may adjust the scale of the simulation control signal 112 output to the game controller 110. For example, a user employing the interface system 102 with an exercise bicycle whose pedaling rate controls the speed of a vehicle in a racing game may begin play with a first rate of motion of the exercise bicycle corresponding to a first vehicle speed in the game. As the user tires during play and their rate of pedaling slows, they may adjust the scale of the simulation control signal 112 such that the first predetermined pedal rate corresponds a second, higher vehicle speed in the game. In one embodiment, such a user-adjustable scale adjustment may be provided by a potentiometer dial which adjusts the magnitude of the simulation control signal 112 and is mounted to the interface system 102.

In general, it will be appreciated that the processor 402 can include one or more of computers, program logic, or other substrate configurations representing data and instructions, which operate as described herein. In other embodiments, the processors can include controller circuitry, processor circuitry, processors, general purpose single-chip or multi-chip microprocessors, digital signal processors, embedded microprocessors, microcontrollers and the like.

Furthermore, it will be appreciated that in one embodiment, the program logic may advantageously be implemented as one or more components. The components may advantageously be configured to execute on one or more processors. The components include, but are not limited to, software or hardware components, modules such as software modules, object-oriented software components, class components and task components, processes methods, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables.

Another embodiment of an interface system 500 comprising a wireless interface is illustrated in FIG. 5. In one embodiment, the interface includes an interface component 502 that is configured to receive one or more wireless signals 510 from one or more sensors 504. As further shown in FIG. 5, the interface component 502 can be in communication 512 with an existing gaming device or platform 520 that allows playing of a game 522. The gaming platform 520 can be in communication 514 with a display/sound device, such as a monitor, so as to provide visual and audio effects for the player.

As shown in FIG. 5, the interface component 502 is shown to provide an input signal 512 to the gaming platform 520. In one embodiment, such an input signal can be configured to be in a standardized format that is understandable by the gaming platform 520. Additional details on how such input signals can be incorporated into the gaming platform 520 are discussed above.

FIG. 6 shows that the one or more wireless sensors 504 can be used in a situation where the player 600 is engaged in a movement-related activity such as exercising. For example, the player 600 may be running on an exercise machine 602 such as a treadmill. Other exercise machines 602 such as exercise bicycles, stair-climbers, elliptical machines, and the like, can also be contemplated, as discussed below in Example 1. In alternative embodiments, the player 600 may be engaged in a sport simulation, such as a boarding sport, using a boarding sport simulation device 2200 (FIG. 22), as discussed below in Example 2. It may be understood, however, that use of the wireless sensors 504 do not necessarily require use of the exercise devices or boarding sport simulators. The wireless sensors 504 can detect motions of the player's body parts without such devices. It may be further understood that embodiments of the present disclosure may be employed with any motion-related activity performed by the player 600, such as aerobic motions and combat type movements, without limit.

As shown in FIG. 6, the player 600 running on the example exercise machine 602 is shown to wear one or more wireless sensors 504. The sensor 504 can be worn at, for example, wrist and/or ankle. In one embodiment, the sensor 504 can be packaged so that it can be removably attached to the player 600. For example, the packaged sensor assembly can include attachment devices such as buttons, snaps, and/or hook and latch fasteners to allow wrapping around the ankle in a secure manner.

In one embodiment, as the player 600 runs on the treadmill 602, the sensor 504 can detect a pace of motion and transmit a corresponding signal to the interface component 502. In another embodiment, as the player 600 simulates a boarding sport activity with the boarding sport simulation device 2200, the sensor 504 can detect movements such as leaning and jumping and transmit a corresponding signal to the interface component 502. The interface component 502 can then convert the wireless signals 510 to a signal provided to the gaming platform 520. The gaming platform 520 can be connected to a monitor 524 that displays the game being played.

In one embodiment, the wireless signals 510 originating from the sensors 504 and provided to the gaming platform 520 can be configured so as to provide logically similar inputs for the gaming platform 120. For example, suppose that a car racing game is being played while the player is running on the treadmill 602. The pace of running can be logically similar to how fast the car is driven. Thus, if the player wishes to speed up his or her car, he or she can run at a faster pace. On the other hand, if the player wants to slow down his or her car, he or she can slow the running pace.

In one embodiment, the interface component 502 can be configured so that its output is in a format compatible with any given gaming platform 520. Thus, the wireless sensor 504 and its communication link with the interface component 502 do not require configuration for any particular dedicated format.

In one embodiment, the interface component 502 can be configured so that its output can override one or more controls associated with the game being played on the gaming platform Additional information regarding the overriding capability is described below, as well as above with respect to the interface component 102.

FIG. 7 shows a block diagram of one embodiment of the wireless sensors 504. The sensors 504 can include a motion sensor 700 that detects motion, and a processor 702 configured to process the signal generated by the motion sensor 700. The sensors 504 can further include a transmitter 704 configured to transmit the wireless signal 510 corresponding to the processed motion-sensor signal. In one embodiment, the signal generated by the sensors 504 may represent movement in a single dimension, such as a straight line in a Cartesian coordinate system. In alternative embodiments, the signal generated by the sensors 504 may represent movement in a plurality of dimensions, such as movement within two or three dimensions.

In one embodiment, the sensor 504 can include a power source 706 such as a battery for providing power to the motion sensor 700, processor 702, and/or transmitter 704.

FIG. 8 shows that in one embodiment, the motion sensor 700 of the wireless sensor 504 can be an accelerometer 800. The accelerometer 800 is shown to output a signal “x” associated with motion of the player 600, and the processor 702 is shown to convert the accelerometer signal “x” to a processed signal “S(x)” for transmission.

In one embodiment, the wireless sensor 504 can include one accelerometer. In one embodiment, the wireless sensor 504 can include more than one accelerometer. In one embodiment, more than one accelerometer can be oriented so as to allow detection of acceleration along different directions.

FIGS. 9A and 9B show examples of how an output from the accelerometer 800 can be processed to estimate the pace of movement of the player 600. In certain exercise movements such as cycling, an ankle-worn wireless sensor 504 can be continuously under centripetal acceleration a=v²/r (v=tangential speed of the pedal, and r=radial displacement of the pedal). Thus, a faster pace of pedaling can result in greater measured acceleration by the sensor 504, such as an accelerometer 800. Such measured acceleration can be output as a voltage “V” that is proportional to the acceleration. Thus, the processor 702 can estimate the rate of motion based on the output voltage, and generate a signal S(V) as a function of V for transmitting.

In certain movements, the acceleration may fluctuate. For example, assuming that a player's ankle generally moves forward and rearward in a cyclic manner, the corresponding acceleration of the ankle may be generally sinusoidal. In such situations, the processor 702 can be configured to process, for example, some non-zero acceleration value (for example, RMS value) indicative of the back-and-forth pace.

In another example, as shown in FIG. 9B, the processor 702 can be configured to detect the frequency “f” of the cyclic signal output by the accelerometer 800, where the frequency can be indicative of the rate of motion of the player 600. Based on the detected frequency, the processor 702 can generate an output signal S(f) as a function of f for transmitting.

Other motion-detecting configurations are possible. In one embodiment, a plurality of sensors 504 may be employed by the player 600. For example, sensors 504 may be placed on the user's wrists, ankles, waist, shoulders, and combinations thereof. Each of the sensors 504 sense the user's motion and transmit a corresponding signal to the interface component 502, as discussed above.

FIG. 10 shows a block diagram of one embodiment of the interface component 502 configured to receive and process the wireless signals 510 from the sensors 504 (not shown). The interface component 502 can include a receiver 1000 configured to receive the signals 510 and generate a signal for processing by a processor 1002. In one embodiment, as previously discussed, the processor 1002 can be configured so that its output 512 is compatible with the gaming platform 520. In one embodiment, as also previously discussed, at least some of the output can override one or more controls associated with the game being played on the gaming platform.

FIG. 11 shows one embodiment of a process 1100 that can be performed by the wireless sensor (for example, the wireless sensor 504 of FIG. 5). In block 1102, an input signal is obtained from the accelerometer. In block 1104, the process 1100 generates a wireless signal based on the accelerometer signal.

FIG. 11B shows one embodiment of a process 1106 that can be performed by the interface component (for example, the component 502 of FIG. 5). In block 1112, a wireless signal is received. In block 1114, the process 1114 generates a signal for the gaming platform based on the received wireless signal.

In one embodiment, the formatting of signals for the gaming platform 520 can be performed by the interface component 502 based on the received wireless signal (which is based on the accelerometer signal). In one embodiment, at least some of such formatting for the gaming platform 520 can be performed prior to wireless transmission by the wireless sensor. FIG. 12A shows one embodiment of a process 1200 that can provide the functionality of the latter, and FIG. 12B shows one embodiment of a process 1210 that can provide the functionality of the former.

As shown in FIG. 12A, the process 1200 in block 1202 receives an accelerometer signal. In block 1204, the process 1200 generates a formatted signal for the gaming platform based on the accelerometer signal. In block 1206, the formatted signal is transmitted wirelessly. Such wireless formatted signal can be received and directed to the gaming platform.

As shown in FIG. 12B, the process 1210 in block 1212 receives an accelerometer signal. In block 1214, the process 1210 generates a wireless signal based on the accelerometer signal for wireless transmission. In block 1216, the wireless signal is transmitted. In block 1220, the wireless signal is received, and a formatted signal is generated for the gaming platform based on the received wireless signal.

FIGS. 13A and 13B show example embodiments where the gaming system 520 of the present disclosure can be configured to allow wireless inputs from a plurality of players. For example, two or more players 600A, 600B can wear respective wireless sensors 504 that transmit on separate channels. Thus, the first player 600A can wear a first sensor that transmits via a first channel (1300A in FIG. 13A, and 1306A in FIG. 13B); and the second player 600B can wear a second sensor that transmits via a second channel (1300B in FIG. 13A, and 1306B in FIG. 13B).

In one embodiment as shown in FIG. 13A, a first interface component 502A can be configured to provide interface functionalities between the first player 600A and the gaming platform 520 (via a link 1304A). Similarly, a second interface component 502B can be configured to provide interface functionalities between the second player 600B and the gaming platform 520 (via a link 1304B). By way of example, certain gaming platforms 520 can have two or more input ports for two or more controllers. In one embodiment, each of such two or more input ports can receive input signals from its corresponding interface component. Thus in the example shown in FIG. 13A, the first interface component 502A can provide input signal via a first input port, and the second interface component 502B can provide input signal via a second input port.

In one embodiment as shown in FIG. 13B, the interface component 502 can be configured to process the two or more channels of wireless signals. For example, a first wireless signal 1306A from the first player 600A and a second wireless signal 1306B from the second player 600B can be processed by the interface component 502.

In one embodiment, the interface components 502A, 502B can provide inputs 1306A, 1306B to the gaming platform 520 via two or more input ports (such as the example described above in reference to FIG. 13A). Other configurations are possible.

FIG. 14 shows that, in one embodiment, the interface component 502 and/or a plurality of sensors 504A, 504B can include a channel selector component (1416 for the interface 502 and 1418A, 1418B for the sensors 504A, 504B). In one embodiment, the channel selector functionality can be configured so that the wireless signal 1404A associated with one sensor 504A does not interfere with the operation of the other channel 1404B.

In one embodiment, the channels associated with the sensors 504A, 504B can be selected manually, for example, by switches. In one embodiment, channel selection for the sensors can be achieved in an automatic manner.

FIGS. 15A and 15B show example processes that can perform the channel selection for the plurality of sensors. In one embodiment as shown in FIG. 15A, a process 1500 can include block 1502 where a receiver is set to receive on a default channel. In block 1504, a transmitter sends to the receiver, using the default channel, a new channel it intends to change to. In one embodiment, such new channel can be selected randomly or in some other manner from a set of available channels. In block 1506, the receiver changes its channel from the default channel to the new channel indicated by the transmitter. In block 1508, the transmitter changes to the new channel and transmits using the new channel.

In one embodiment as shown in FIG. 15B, an example process 1510 can perform an automatic channel selection. In a decision block 1512, the process 1510 determines whether another wireless signal has been detected. If “Yes,” the process 1510 in block 1514 can facilitate switching of channel for a selected sensor. For example, if the first sensor is operating on channel A, the second channel detected can be assigned to channel B. In the answer to the decision block 1512 is “No,” the process 1510 can bypass the channel-assigning step of the process block 1514. In block 1516, the process 1510 continues to operate at the new or existing channel configuration.

In some embodiments, it may be desirable to be able to adjust the sensitivity of the signals associated with the wireless sensor. For example, some movements may involve much greater acceleration and/or speed. For such movements, the player may want to reduce the sensitivity of the sensor so as to not saturate the input for the gaming platform. On the other hand, some movements may not involve much acceleration and/or speed. For such movements, the player may want to increase the sensitivity of the sensor so as to enhance the effects of slight motions.

FIGS. 16A and 16B show non-limiting example configurations that can facilitate the sensitivity adjustment feature. In one embodiment, as shown in FIG. 16A, a sensitivity adjustment component 1606 can be part of the interface component 502. In one embodiment, the adjustment component 1606 can globally reduce or increase the sensitivity of all channels 1604A, 1604B associated with sensors 504A, 504B. In one embodiment, the adjustment component 1606 can be configured to selectively adjust one or more channels.

In one embodiment, as shown in FIG. 16B, each sensor 504A, 504B can include an adjustment component 1616A, 1616B. Thus, each channel 1614A, 1614B can include a wireless signal configured to include the sensitivity adjustment.

Other configurations are possible. For example, any combination of features shown in FIGS. 16A and 16B are possible.

In some embodiments, the interface component 502 can be connected directly to the gaming platform 520 so as to provide at least some of the commands associated with the game. For example, the interface component 502 can be plugged into one socket of the gaming platform 520, and the game controller can be plugged into another socket.

In some embodiments, FIG. 17, the interface component 502 can be connected to a game controller 1700, so that the wireless signal from the sensors 504 can be formatted and sent through the same path (to the platform) as that of the controller 1700. In alternative embodiments, the interface component 502 may be in wireless communication with the game controller 1700. FIG. 17 shows one embodiment of a game controller 1700 configured to provide game control signals to the gaming platform 520 (not shown) via a connection 1702. As shown, an interface 502 can be also connected to the controller 1700 so as to provide sensor-originating signals to the hand controller 1700 that in turn can send such signals to the gaming platform.

FIG. 18 shows a photograph of one embodiment of the interface 260 plugged into one embodiment of the hand controller 1700 via the cable 1702. The hand controller 1700 is also shown to be connected to the gaming platform (not shown) via the cable 1702. The example interface 502 is shown to include a sensitivity adjustment wheel 1712 for adjusting the sensitivity of accelerometer based signals. Also, in one embodiment, the example modular connectivity is via an RJ-12 type jack/plug assembly.

In one embodiment, the connection between the interface 502 and the hand controller 1700 can be removable. For example, a jack/plug assembly 1704 can allow a cable 1706 to be connected or disconnected to/from the hand controller 1700. In one embodiment, such modular connectivity can allow the hand controller 1700 to operate in its standard mode, without input from the sensors 504, when the interface 502 is disconnected.

Also shown in FIG. 17 is a wireless sensor 504. The example sensor 504 is configured to allow automatic channel selection when a second sensor is operating, and/or when the current channel is noisy or unreliable. For the example sensor 504 and the interface 502, the wireless communication is via 2.4 GHz RF signal. Other types and/or frequency signals are possible.

As discussed above, the interface component 502 can be configured so that its output can override one or more control functions, provided by the hand controller 1700, that are associated with the game being played on the gaming platform, as discussed above.

In further embodiments, the control functions that are overridden are also configurable. The wireless signal 510 sent to the interface component 502 may be configured to not only provide control functions for the gaming platform 520 but also to provide instructions to the interface component as to what control functions of the hand controller 1700 are to be overridden by the control input.

The choice of which control functions are overridden may be user-selectable In one embodiment, the sensor 504 may be configured to operate in a plurality of modes, where each mode is distinguished by the control functions which the interface component 502 overrides. For example, one mode may comprise a basic mode, where a small number of control functions are overridden by the sensor output. Such a basic mode may allow the player 600 to gain familiarity with using the sensor 504, without the complexity of controlling all of the control functions which the sensor 504 might possibly provide. Another mode may comprise an advanced mode, where a large number of control functions are overridden by the sensor output. The advanced mode may be appropriate for experienced players seeking the maximum realistic experience which the interface system is capable of providing. Modes intermediate to basic and advance may also be provided.

In certain embodiments, overridden control functions may be manufacturer configured in a plurality of modes, as discussed above, and chosen through at least one of hardware settings of the interface system and software settings of the gaming platform 520. In alternative embodiments, a plurality of the overridden control functions may be selected individually by the user through at least one of hardware settings of the interface system and software settings of the gaming platform 520.

It may be understood that the configurability of the overridden control functions in this manner may also be implemented in embodiments of the interface system 102.

In one embodiment, the hand controller 1700 can also include a selector switch 1710 that can disable the input from the interface 502. In one embodiment, such disabling can occur even if the interface 502 is plugged in and sending signals.

In one embodiment, as shown in FIG. 17, the interface 502 connected to the controller 1700 can receive wireless signals 510 from the sensor 502 so as to provide the various functionality as described herein.

In general, it will be appreciated that the processors can include, by way of example, computers, program logic, or other substrate configurations representing data and instructions, which operate as described herein. In other embodiments, the processors can include controller circuitry, processor circuitry, processors, general purpose single-chip or multi-chip microprocessors, digital signal processors, embedded microprocessors, microcontrollers and the like.

Furthermore, it will be appreciated that in one embodiment, the program logic may advantageously be implemented as one or more components. The components may advantageously be configured to execute on one or more processors. The components include, but are not limited to, software or hardware components, modules such as software modules, object-oriented software components, class components and task components, processes methods, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables.

EXAMPLES

In the following examples, further embodiments of simulation devices 108 for use with the interface system 102 discussed above are illustrated. It may be understood, however, that the simulations devices 108 may also be used in conjunction with embodiments of the interface system 500. The examples illustrate the capabilities of embodiments of the interface systems 102, 500 to provide an enhanced gaming experience for users of gaming devices. These examples are discussed for illustrative purposes and should not be construed to limit the embodiments of the invention.

Example 1 Exercise Device Simulator

FIG. 19 illustrates one embodiment of the interface system 102 used in conjunction with an exercise device 1900, for example, an exercise bicycle 1900. The exercise bicycle 1900 generally comprises a support base 1902, a seat 1904, a set of handlebars 1906, and a wheel 1910 joined to pedals 1912 by a crankshaft 1914. In general, the interface system 102 is interconnected to the exercise bicycle 1900 and the gaming device 104 (not shown). So configured, the interface system 102 senses one or more simulation parameters representative of a moving portion of the exercise bicycle 1900 and uses the measured simulation parameters to provide one or more control functions 300′ to a game played on the gaming device 104. As discussed above, in certain embodiments, the control functions 300′ based on the motion of the bicycle 1900 may override corresponding control functions provided by the game controller 110.

In one embodiment, illustrated in FIG. 19, the game controller 110 can be reversibly mounted to the handlebars 1906 of the bicycle 1900. Advantageously, when so mounted, the controls of the game controller 110 are within easy reach of the hands of the user while employing the exercise bicycle 1900. Alternatively, the user may hold the game controller 110 in their hands while using the exercise bicycle 1900.

FIGS. 20A, 20B, and 21 illustrate one embodiment of the sensing component 400 mounted to the exercise bicycle 1900 so as to allow transfer of motion, in a measurable manner, from the exercise bicycle 1900 to the sensing component 400. As illustrated in FIG. 20A, the sensing component 400 includes a rotatable member 2000. In one embodiment, the sensing component 400 is mounted to a structure 2002, such as a bicycle cowling 2002 at a mounting location 2006, allowing the rotatable member 2000 to engage a rotating part, such as the pedal crankshaft 1914. Such engagement can transfer a portion of the rotational motion 2010 of the pedal crankshaft 1914 due to pedaling via the pedal 1912, to the rotatable member 2000, thereby making the rotatable member 2000 rotate, as shown by arrow 2012.

FIGS. 20A-20B further illustrate how embodiments of the sensing component 400 can be configured to couple with the exercise bicycle 1900 so to allow rotational engagement of the rotatable member 2000 with the exercise bicycle 1900. In one embodiment, FIG. 20B, the rotatable member 2000 includes a disk 2014, an aperture 2016, an outer circumferential wall 2020, and an inner circumferential wall 2022. The rotatable member 2000 is configured to divide into two mating halves 2024A and 2024B which pivot with respect to one another about a hinge 2026. The two halves 2024A and 2024B are separated to allow the aperture 2016 to be positioned about the crankshaft 1914. The two halves 2024A and 2024B are joined about the crankshaft 1914 at the mounting location 2006 and secured together by a reversibly locking latch 2030. The sensing component 400 may further comprise a compliant layer 2032 which is interconnected to the inner circumferential wall 2022. This compliant layer 2032, for example a foam, allows the sensing component 400 to accommodate crankshafts 1914 of varying size within the aperture 2016 and provide frictional engagement between the rotatable member 2000 and the crankshaft 1914. This frictional engagement causes the rotatable member 2000 to rotate 2012 when the crankshaft 1914 rotates 2010.

As shown in the embodiment of FIG. 21, the sensing component 400 can be configured to allow sensing of the rotational speed of the rotatable member 2000. In one embodiment, an inner surface 2106 of the outer circumferential walls 2020 moves relative to a sensing element 2100. The sensing element 2100 is mounted to a mounting member 2102 that is positioned at least partially within a space 2104 defined by the disk 2014 and the circumferential walls 2020 and 2022 and is substantially stationary with respect to the rotatable member 2000.

The sensing element 2100 can be configured to detect a rate of relative motion of the inner surface 2106 of the outer circumferential wall 2020 relative to the sensing element 2100. In one embodiment, the sensing element 2100 can comprise an optical sensor that is configured to distinguish between dark and light regions of the inner surface 2106 based on reflectivity. In one embodiment, the sensing element 2100 may comprise a photo reflective type optical sensor. In a preferred embodiment, the optical sensor may comprise a ROHM 800 nm reflective photointerrupter. In one embodiment, where such a sensing element 2100 is used, the inner surface 2106 can define an alternating pattern 2110 of dark and light regions arranged along the circumference of the rotatable member 2000. The inner surface 2106 so configured is hereafter referred to as a sensing surface 2114

In one embodiment, as illustrated in FIG. 21, the sensing element 2100 can be mounted at or near an edge 2112 of the mounting member 2102 so as to be positioned near and radially inward from the sensing surface 2114, with respect to the radius defined by rotation of the rotatable member 2000. In one embodiment, the mounting member 2102 may be affixed to a stationary portion of the exercise bicycle 1900 such as the bicycle cowling 2002 using an adhesive or other fastener. In a further embodiment, the rotatable member 2000 may be rotatably coupled to the mounting member 2102 via a coupling. Such coupling can include a bearing coupling or other couplings that allow rotational movements between two parts. This configuration allows the sensing element 2100 to be positioned substantially within the space 2104 and substantially stationary with respect to the rotatable member 2000.

In alternative embodiments, the pattern 2110 and sensing element 2100 may be arranged at different locations within the sensing component 400 to measure motion of the rotatable member 2000. For example, the pattern 2110 may be placed on the disk 2014 and the sensing element 2100 oriented so as to distinguish between the dark and light regions of the disk 2014.

In one embodiment, a rate of movement of the sensing surface 2114 can be detected by the sensing component 400 based on differences in reflectivity of the dark and light regions of the pattern 2110. In one embodiment, the sensing element 2100 includes an optical emitter and receiver integrated into a modular unit. The sensing element 2100 can transmit radiative emissions, such as light, and detect the reflections from the sensing surface 2114. Circuitry associated with the receiver can be configured to distinguish the difference between reflections from the dark regions and reflections from the light regions.

Detection of such alternating light and dark regions of the sensing surface 2114 by the sensing element 2100 can generate the sensing component signal 404, as illustrated in FIG. 4. In one embodiment, the sensing component signal 404 comprises an analog periodic alternating waveform. In one embodiment, the generated waveform is approximately a square wave form. In one embodiment, such waveform can be fed to the processor 402, configured with a frequency-to-voltage conversion circuit that can transform the analog signal into a relatively stable DC voltage level whose voltage level is indicative of the frequency of the analog signal frequency coming from the sensing component 400. In one embodiment, the output of frequency-to-voltage conversion circuit can fed to a low pass filter that removes high frequency components, leaving a generally constant DC voltage for a generally constant frequency. This DC voltage level can change as the rate of the rotational motion of the crankshaft 1914, and thus the rotational rate of the rotatable member 2000 changes. Subsequently, this DC voltage can be converted to a three-terminal resistance for input into the game controller 110 so as to provide control functions to the game controller 110, as described above.

The design of the sensing component 400 presents several advantages in use. In one advantage, the sensing component 400 may be reversibly mounted to the exercise bicycle 1900. For example, the sensing component 400 is easily removed from the exemplary exercise bicycle 1900 by detaching the mounting member 2102 from the bicycle cowling 2002, unclasping the latch 2030, and separating the mating halves 2024A and 2024B of the disk 2014. Thus, the sensor 106 may be used with multiple exercise bicycles 1900. In further advantage, the sensing surface 2114 and sensing element 2100 are unobtrusive and generally hidden from view so as not to detract from the appearance of the exercise bicycle 1900.

The sensing component 400 described with respect to FIGS. 20A, 20B, and 21 can be attached to various exercise devices, including but not limited to, upright bicycles, recumbent bicycles, treadmills, stair steppers, elliptical cross-trainers, or other exercise device 1900 that has as its base some form of motion inherent in one of its mechanical mechanisms. Such motion can be rotational or translational. In some exercise devices 1900, such as treadmills, both rotational and translational motion can be exposed for coupling. Based on the foregoing description, the sensing component 400 can be adapted to frictionally couple to the translationally moving part, for example, the moving mat.

Example 2 Boarding-Sport Simulation Device

In another embodiment of the interface system 102, illustrated in FIG. 22, the interface system 102 is configured to work in conjunction with a boarding-sport simulation device 2200 for simulating board-based sports such as snow-boarding, skate-boarding, skiing, and surfboarding. As is generally known, such sports involve a rider standing and balancing on a board and moving downhill on snow (in the case of snow-boarding) or rolling on pavement (in the case of skate-boarding). Various maneuvers can be achieved by applying weight on different edges or ends of the board. For example, a right turn (assuming facing forward) can be achieved by applying weight on the right edge of the board.

In some embodiments of the present invention, the boarding sport simulation device 2200 can be configured to allow a user to stand and balance in a manner similar to the actual riding to provide a more realistic gaming experience. While standing on the board, the user can perform various maneuvers similar to realistic situations. For example, a turn can be simulated by applying more weight on one side of the boarding-sport simulation device 2200.

As shown in the embodiment of FIG. 22, the boarding-sport simulation device 2200 can include a board 2202 that is mounted on a pedestal 2204. As described below, the pedestal 2204 can be compressible under the weight of a user 2206 standing on top of the board 2202. Similar to a snowboard or a suspension mounted skateboard, the compressibility of the pedestal 2204 can allow the user to place weight on different portions of the board 2202. Such weight-placement maneuvers can be detected by the sensor 106 and the results used as the simulation device control signal to the game controller 110.

In one embodiment, the interface system 102 measures various boarding maneuvers performed by a user of the boarding-sport simulation device 2200 while the user 2206 simultaneously employs the game controller 110 to provide additional control functions for a boarding sport game.

In further embodiments, the interface system 102 measures user actuation of a plurality of switches 2210. The switches 2210 may be employed by the user 2206 in isolation, with the game controller 110, during the performance of various boarding maneuvers using the boarding sport device 2200, and combinations thereof, in order to provide additional control functions for a boarding sport game.

In some embodiments, control functions 300 of the game controller 110 may be overridden by those control functions 300′ provided by the boarding-sport simulation device 2200, through use of any combination of the switches 2210 or the boarding maneuvers, in the manner discussed above with respect to FIG. 3.

FIG. 23 shows a perspective view of one embodiment of the boarding sport simulation device 2200, where the board 2202 is mounted on the pedestal 2204 in communication with the sensing component 400. In the embodiment of FIG. 23, the sensing component 400 comprises a sensor assembly 2300 in communication with the boarding sport simulation device 2200 to detect boarding maneuvers, such as tilts along more than one direction, and vertical movements, such as hopping, of at least a portion of the boarding sport device 2200 and/or board 2202. The sensor assembly 2300 is configured to output the simulation control signal 112 in order to provide control functions representative of boarding maneuvers performed by the user 2206 to the game controller 110. Examples of the sensor assembly 2300 are described below in greater detail with respect to FIGS. 28 and 30.

FIG. 23 also illustrates embodiments of the switches 2210. The switches 2210 are mounted to the board 2202 in a manner which facilitates easy access and actuation by the hands and/or feet of the user 2206 during use of the board 2202. In one embodiment, the switches 2210 may comprise a plurality of switches 2210A that are positioned on a first planar surface 2302A of the board 2202. For example, the planar switches 2210A may be placed in a location which is approximately centered with respect to the width 2312 of the board 2202 and adjacent an end 2304 of the board 2202. This location is within easy reach of the user's foot when balancing on the board 2202.

Actuation of the switches 2210A may be used to control a variety of features within a boarding sport game. In one embodiment, the switches 2210A may be used to control speed of movement within the boarding sport game. In another embodiment, release of the switches 2210A may cause an in-game action of popping into the air (an “Ollie” maneuver). Alternatively, if the in-game board is already in the air, releasing the switches 2210A may cause the in-game board to move higher in the air than normally achieved with a standard jump maneuver.

In alternative embodiments, the switches 2210 may comprise a plurality of switches 2210B that are positioned on a second planar surface 2302B of the board 2202, the edges 2306 of the board 2202, and combinations thereof. In one example, actuation of the switches 2210B and boarding maneuvers may result in “grabbing” actions where the user 2206 performs in-game actions including grabbing the board with their hands. The particular in-game grabbing action may be dependent on the particular switch 2210B or combination of switches 2210B which are actuated by the user. It may be understood, however, that the discussion of the user's physical movements and the correlation of these movements with in-game movements are provided for exemplary purposes and should not be construed to limit the disclosed embodiments.

The switches 2210 may further comprise any of switches, levers, knobs, and buttons. The switches 2210 may be comprise mechanical switches, non-mechanical switches, and combinations thereof. In certain embodiments, the switches 2210 may comprise a plurality of touch-sensitive switches 2210. For example, the switches 2210 may comprise capacitive contact sensors which switch on and off when touched. In additional embodiments, the switches 2210 may be pressure sensitive, such that the magnitude of an action or effect within the game scales with the amount of pressure applied to the switch by the user 2206.

FIGS. 24A-24C illustrate embodiments of possible mounting locations for the sensor assembly 2300 on or about the boarding-sport simulation device 2200. In one embodiment, FIG. 24A shows that the sensor assembly 2300 can be coupled to the underside of the board 2202. A cavity 2400 can be formed on the pedestal 2204 to accommodate the sensor assembly 2300. In one embodiment, a cable 2402 connects the sensor assembly 2300 to the gaming device 104. In certain embodiments, the cable 2402 may comprise a plurality of segments, for example 2402A and 2402B, which are joined by a plurality of connectors 2404. In another embodiment, illustrated in FIG. 24B, the sensor assembly 2300 does not need to be contained within the pedestal 2204. In this embodiment, the sensor assembly 2300 is shown to be coupled to the underside of the board 2202 but outside the pedestal 2204. In a further embodiment, illustrated in FIG. 24C, the sensor assembly 2300 does not need to be placed under the board 2202. In this embodiment, the sensor assembly 2300 is shown to be coupled to the upper side of the board 2202. In additional embodiments, a plurality of sensor assemblies 2300 may be employed at the positions discussed above in any combination. Thus, based on the foregoing embodiments, it will be appreciated that the sensor assembly 2300 can be positioned at many different locations on or about the board 2202, as required, to measure boarding maneuvers performed using the boarding-sport simulation device 2200.

FIGS. 25A-25D illustrate different embodiments of the shape of the pedestal 2204. For example, the pedestal 2204 can have a generally circular cross-sectional shape (FIG. 25A), a generally elliptical shape (FIG. 25B), or a rectangular shape (FIG. 25C). Additionally, more than one pedestal 2204 may be utilized in the boarding simulation device 108 (FIG. 25D). In some embodiments, the shape and size of the pedestal 2204 may be selected based on criteria such as the desired stability or desired mechanical response of the pedestal 2204 when under compression by the weight of the user.

In some embodiments, the mechanical response of the pedestal 2204 may be influenced by the choice of material composition for the pedestal 2204. These mechanical properties may include, but are not limited to, stiffness, elastic modulus, and relaxation modulus. For example, foam or foam-based materials having desired mechanical properties can be used to form the pedestal 2204 so that when the user 2206 leans into a given direction, the pedestal 2204 can deform in that direction in a manner similar to the snow (for snowboarding) or the suspension (for skateboarding).

In some embodiments, it is not necessary for the pedestal 2204 to adopt a block-type structure, as illustrated in FIG. 26A-26D. To simulate various motions on the boarding-sport simulation device 2200, the pedestal 2204 may include other structures or components that allow for generally restorative motions, such as tilts. In one embodiment, illustrated in FIG. 26A, the pedestal 2204 may comprise one or more springs 2600. The position, number, and mechanical response of one or more of the springs 2600 may be varied as described above.

In another embodiment, illustrated in FIG. 26B, the pedestal 2204 can be configured to make the boarding-sport simulation device 2200 unstable. This instability provides greater maneuverability and challenge when using the boarding-sport simulation device 2200. For example, a rounded member 2602, such as a hemisphere, can be used as a pedestal 2204 so that the rounded surface 2608 of the member 2602 engages the floor 2604 at a contact point 2606.

In some applications, it may be desirable to moderate the degree of instability of the boarding-sport simulation device 2200. For example, as shown in FIG. 26C, a dampening material 2610, such as foam, can cover the surface 2608 of the rounded member 2602 so that under weight and maneuvers, the dampening material 2610 can compress in a generally restorative manner. In another example, the rounded member 2602 can be formed from a reversibly compressible material, so that under weight, the rounded member 2602 can deform in a generally restorative manner.

In an alternative embodiment, illustrated in FIG. 26D, the pedestal 2204 can further include a damper member 2612 positioned about the contact point 2606 so as to provide dampening of the rocking of the rounded member 2602. Such rocking can result from the tilting movements of the boarding-sport simulation device 2200. In one embodiment, the rounded member 2602 can be a hemisphere. In one embodiment, the damper member 2612 can be a donut-shaped member that substantially surrounds the contact point 2606, thereby providing dampening functionality for tilts.

As shown and described herein, there are many different types and configuration of pedestals 2204 that can support the board 2202 so as to allow performance of various boarding maneuvers. Thus, the examples shown and described in reference to FIGS. 25A-25D and FIGS. 26A-26D should be understood as non-limiting examples.

FIGS. 27 and 28 show that in some embodiments, the sensor assembly 2300 can be configured to detect tilts along two directions defined in a plane that is substantially co-planar with the board 2202. For the purposes of description, a non-limiting example of a coordinate system 2700 is depicted in FIG. 27, where an X-direction 2702 can be transverse to the longitudinal axis of the board 2202 and a Y-direction 2704 can be parallel to the longitudinal axis of the board 2202.

Based on this coordinate system 2700, FIG. 28 illustrates that in one embodiment, the sensor assembly 2300 can include transverse and longitudinal sensor components 2800 and 2802 that are respectively configured to detect X-direction 2702 and Y-direction 2704 components of a given tilt. The sensor assembly 2300 further includes the processor 402 to process sensing component signals 404 from such sensor components 2800 and 2802 and output the simulation control signal 112. This simulation control signal 112 can provide one or more control functions to the game controller 110 for playing a boarding-sport game, as discussed above. In one embodiment, the sensor components 2800 and 2802 may comprise one or more accelerometers that are configured to detect tilts along the X- and Y-directions 2702 and 2704.

In one embodiment, the tilt in the X-direction 2702 of the boarding-sport simulation device 2200 can be used to control left and right turns in a game played on the gaming device 104. A user leaning left or right on the board 2202 can affect a tilt having a transverse component which is detectable by the transverse tilt sensor component 2800. The resulting sensing component signal 404 output by the transverse tilt sensor component 2800 can be processed by the processor 402 to provide a simulation control signal 112 representative of the transverse tilt. When received by the game controller 110, this simulation control signal 112 may override the corresponding control function on the game controller 110, such as a left or right thumbstick motion. Thus, the transverse leaning motion of the user of the boarding-sport simulation device 2200 results in a corresponding left or right turn in the game.

In one embodiment, a tilt in the Y-direction 2704 of the boarding-sport simulation device can be used to increase or decrease speed in a game played on the gaming device 104. A user leaning forward or backward on the board 2202 can affect a tilt having a longitudinal (Y-direction) component which is detectable by the longitudinal tilt sensor component 2802. The resulting sensing component signal 404 output by the longitudinal tilt sensor 2802 can be processed by the processor 402 to provide a simulation control signal 112 representative of the longitudinal tilt. When received by the game controller 110, this simulation control signal 112 overrides the corresponding control function on the game controller 110, such as up or down thumbstick motion. Thus, the longitudinal leaning motion of the user of the boarding-sport simulation device 2200 results in a corresponding increase or decrease in speed.

In one embodiment, combinations of longitudinal and transverse tilts may also be performed simultaneously on the boarding-sport simulation device 2200 as described above to provide multiple game control functions. For example, a user may lean forward and to the right to effect a right turn while concurrently increasing speed in the game. It may be understood that alternative function control configurations for the boarding sport simulation device 2200 are possible and that that those described above are non-limiting examples.

In some embodiments, the sensor assembly 2300 can also be configured to detect one or more motions other than, or in addition to, the X-direction 2702 and Y-direction 2704 tilts described above. In one embodiment, the sensor assembly 2300 measures tilts in the X-direction 2702 and Y-direction 2704, as described above, as well as motions along a Z-direction 2900. The Z-direction 2900 extends generally perpendicular to the plane defined by the X- and Y-directions 2702 and 2704, as illustrated in FIG. 29. In one embodiment, the Z-direction 2900 motion of the boarding-sport simulation device 2200 can simulate board maneuvers such as hopping.

For example, FIGS. 29 and 30 show that, in one embodiment, the sensor assembly 2300 can further include one or more sensing components 400 configured to measure motion along three dimensions, including vertical motions out of the plane of the board 2202. In one embodiment, the sensing components 400 comprise a Freescale 3-axis +/−1.5 g accelerometer. In an alternative embodiment, sensor assembly 2300 may include a single semiconductor device configured to measure acceleration along three axes. Signals from the sensing components 400 of the sensor assembly 2300 can be processed by the processor 402 and output as the simulation control signal 112 in a manner similar to that described above in reference to FIGS. 27-28.

FIG. 31 shows that in some embodiments, the system can detect additional boarding maneuvers for use as control functions 300′ for a game. As is generally known, either end of the board 2202, such as a skateboard or snowboard, can be swung to perform maneuvers such as turning or sliding. To accommodate simulation of such end-motion maneuvers, the interface system 102 may further comprise one or more end-swing sensor components 3100. The end-swing sensor components 3100 may be positioned at a front-end 3102A or a rear-end 3102B of the boarding sport simulation device 2200 to detect swinging or rotational motions, depicted as arrows 3104A and 3104B, respectively. Thus, the end-swing sensor component 3100 positioned at the front end 3102A of the board 2202 can detect swinging or rotational motions 3104A at the front end 3102A of the board 2202. Similarly, the end swing sensor component 3100 positioned at the rear end 3102B of the board 2202 can detect swinging or rotational motion at the rear-end 3102B of the board 2202.

As further shown in FIG. 31, the boarding-sport simulation device 2200 can utilize a plurality of the end-swing sensor components 3100. In one embodiment, such end-swing sensor components 3100 can be used in conjunction with the sensor assembly 2300 configured to operate as described above in reference to FIGS. 27-30 to detect tilts. In one embodiment, sensing component signals 404 from the end-swing sensors 3100A and 3100B can be processed by the processor 402 in the manner described above in reference to FIGS. 27-30.

FIGS. 32A-32C show an example of how a tilt can be detected by the transverse tilt sensor 2800 of the tilt assembly 2300 so as to produce sensing component signals 404 representative of the tilt. FIG. 32A shows one embodiment of the boarding-sport simulation device 2200 when the user (not shown) is not leaning to any side. In such a riding position, the sensing component signal 404 output by the transverse tilt sensor 2800 may comprise a voltage signal V_(x) indicative of the transverse tilt which can be set at V₀.

In FIG. 32B, the boarding-sport simulation device 2200 is shown when the user leans on the left side of the boarding-sport simulation device 2200 (depicted as an arrow 3200), thereby compressing the left side of the pedestal 2204. Such a tilt to the left can be detected by the transverse tilt sensor 2800, which generates a sensing component signal 404 comprising a voltage signal V_(x)=V₁. In this example, the tilt is depicted as being in the negative X-direction and, in one embodiment, the voltage assigned to such a movement can be assigned a voltage that is more negative than the “no-lean” voltage V₀.

In FIG. 32C, the user is shown to lean even more on the left side, as depicted in an arrow 3202. Such a tilt can be detected by the transverse tilt sensor 2800, which generates a sensing component signal 404 comprising a voltage signal V_(x)=V₂, which is more negative than V₁.

In further embodiments, motion in the Y- and Z-directions 2704 and 2900 may be similarly configured. For example, the degree of motion in the Y- and Z-directions 2704 and 2900 may be detected and result in a sensing component signal 404 comprising a DC voltage whose magnitude depends on the amount of tilt and whose sign (positive or negative) depends on the direction of the tilt. It will be understood that alternative voltage assignments for a given degree and direction of tilt may also be utilized.

FIG. 33 shows non-limiting examples of boarding maneuvers that can be detected and used as control functions for a game using the various techniques disclosed herein. Such board motions may include, but are not limited to, side tilts 3300A and 3300B, end tilts 3302A and 3302B, vertical motions 3304 (such as hopping), and end swings 3306A and 3306B.

FIGS. 34A-34E show that the various features of the embodiments of the present invention can also be applied for simulation of sports such as skiing. The board 2202 of the boarding-sport simulation device 2200 may comprise skis 3400. The skis 3400 may have a single slat or two or more slats 3402A and 3402B. For skis 3400 possessing a single slat, various motion simulations can be achieved in a manner similar to that described above.

In one embodiment, the skis include two slats 3402A and 3402B. For example, the two slats 3402A and 3402B can be collectively referred to as the board 2202. In the embodiment of FIG. 34, each of the slats 3402A and 3402B is shown to have its own sensor assembly 2300. In one embodiment, one or more sensor assemblies 2300 can be positioned on a given ski 3400 and used in a manner similar to that described above.

As shown in the embodiment of FIG. 34A-34E, the two slats 3402A and 3402B can be positioned on various configurations of the pedestal 2204. In non-limiting examples, FIGS. 34B and 34C show that the pedestal 2204 can cover one section 3404 (FIG. 34B) along the longitudinal direction of the slats 3402A and 3402B or more than one section 3404 (FIG. 34C). Also, in a non-limiting example, FIG. 34D shows that a given pedestal 2204 can cover both slats 3402A and 3402B. In a further non-limiting example, FIG. 34E shows that each of the slats 3402A and 3402B can be supported by a separate pedestal 2204. Alternative configurations are also possible.

In one embodiment, the example pedestals 2204 of FIGS. 34A-34E can be configured in a manner similar to that described above.
